Abstract
An antenna, where an end point of a radiator is shorted, using coupling matching is disclosed. The antenna includes a first conductive element connected electrically to a first ground, a second conductive element connected electrically to a feeding part, and spaced from the first conductive element by a certain distance, a third conductive element extending from the first conductive element and configured to output a RF signal, an end point of the third conductive element being coupled to a second ground. Here, the first conductive element and the second conductive element have a certain length so that a travelling wave is generated and enough coupling is provided. The antenna provides wide band characteristics while maintaining a low profile structure. The frequency characteristics of the antenna are not changed significantly due to external factors such as hand effect and head effect.
